P2615 Camshaft position signal output circuit voltage low

Camshaft position signal output circuit low

P2615 in short

P2615 means the engine computer saw a low voltage on the circuit that passes the camshaft position signal on to other systems. On 2022-2024 Nissan Versa manual models it shows up with a power-limiting fail-safe after a stall, which Nissan fixes under a bulletin. Get it checked soon; pull over if power drops in traffic.

The engine computer reads the camshaft position sensor and passes that timing signal on to other systems that need it. P2615 sets when the voltage on that output circuit stays lower than it should.

In practice almost every report of this code comes from the 2022-2024 Nissan Versa with a manual transmission. Owners describe the car suddenly holding to 20-40 mph with the pedal on the floor, often after a stall, with P2615 stored (sometimes only as a pending code with no warning light). A full restart usually clears it until next time.

NHTSA opened investigation PE24007 into this condition. It found that if the engine stalls and is restarted within about five seconds, the engine computer goes into a limited-torque fail-safe. Nissan's bulletin NTB25-024 replaces the valve timing control unit and updates the software on cars built through 9 July 2024, at no charge, and NHTSA closed the investigation in October 2025.

Most likely causes

  1. Valve timing control unit and software (2022-2024 Versa manual)

    Supported by vehicle data
    Why it ranks here
    NHTSA's investigation of the Versa manual describes a limited-torque fail-safe after a stall and quick restart, fixed by Nissan bulletin NTB25-024 (new valve timing control unit and software). Owners and a Nissan dealer tie P2615 to the same power loss.
    What would change this
    Rises on a 2022-2024 Versa with a manual transmission built before 9 July 2024 that has not had the bulletin done; falls on other vehicles or after the repair.

  2. Wiring or connector fault in the camshaft signal circuit

    Possible — needs testing
    Why it ranks here
    A low-voltage code on any circuit can come from a chafed wire or poor connector. No bulletin we found names this for P2615, so it ranks below the Versa fix.
    What would change this
    Rises on other vehicles, or if the code stays after the Versa bulletin is done; rises if wiring near the camshaft sensor is damaged or corroded.
    How to test the camshaft position sensor

What to test first

Start at step 1. Each result tells you what it means and where to go next.

  1. Note whether the car is a 2022-2024 Nissan Versa with a manual transmission, and whether the power loss followed a stall and quick restart.

    Low risk

    • IfIt is a Versa manual and the power loss followed a stall

      It meansNissan's bulletin NTB25-024 likely applies.

      Go to step 2

    • IfAny other vehicle

      It meansHave the circuit diagnosed.

      Go to step 3

  2. Ask a Nissan dealer to check your VIN for bulletin NTB25-024 and whether it has already been done.

    Low risk

  3. Have a shop read freeze-frame data and check the camshaft signal circuit and connectors with a wiring diagram.

    Best left to a shopTool: scan tool, multimeter, wiring diagram

    Warning:Testing is done with the engine running near moving belts and hot parts. Leave it to a shop.

Symptoms

  • Check engine light, or a pending code with no light
  • Problem clears after switching off fully and restarting
  • Car will not accelerate past about 20-40 mph with the pedal down Gets more serious: stop and have it checked.
  • Engine stalls, then runs with very little power Gets more serious: stop and have it checked.

How to fix

  1. On a 2022-2024 Versa with a manual transmission, ask a Nissan dealer whether bulletin NTB25-024 covers your VIN.

  2. Until it is fixed, if the engine stalls, wait a few seconds before restarting.

    Supported by vehicle data

    Manual transmission only. A stall followed by a quick restart puts the engine into a limited-power fail-safe; owners report P2615. Nissan bulletin NTB25-024 replaces the valve timing control unit and updates software on cars built through 9 July 2024, at no charge.

P2615 questions

Why does my Versa lose power after a stall?

On 2022-2024 manual Versas, restarting within about five seconds of a stall puts the engine into a limited-power fail-safe. Nissan's bulletin NTB25-024 fixes it free of charge on cars built through 9 July 2024.

Why does P2615 go away after a restart?

Owners report the low-power mode clears after switching off fully and restarting. The underlying fault is still there, so have the bulletin checked.
